To all when] 7'13 'IIIIIIII/ concern:

Be it known that I, CARL O. LILJEROS, a citizen of the United States, and a resident of the borough of Brooklyn, city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Envelop-Closing M achines, of which the following is a specification, taken in connection with the accompanying drawings, which form apart. of the same. 1

This invention relates to envelop-closing machines, and relates especially to machines which effect the closing of envelope b y tuck ing in the flaps of the envclops, so as to form asecurc but unsealed closure for the same.

In the accompanying drawings, inwhich the same refcrenccnunieral refers to similar arts in the several fi ures Fi ure 1 is a longitudinal section of a machine embodying this invention. Fig. 2 18 a transverse section of the same. Fig. 3 is a partial side view.

Fig. 4 is a partial horizontal section. Figs. 5, 6, 7, and 8 are diagrannnatic sectional views showing the operation of amachine.

In the illustrated embodiment of this invention a rigid frame is formed of the side pieces 1, which are rigidly held together by the transverse braces 2 and 39. A suitable runway extends longitudinally of the machine to guide the envelops therethrough, the body of this runway being formed of slot ted construction and comprising a series of longitudinally-arranged strips 3. The two lateral guides 14 are transversely adjustable, so as to adjust the width of runway and accommodate envelops of different size These guides may be adj usted by any desired means and, as indicated in the drawings, each of the guides is formed with a suitable lug 12, which. projects through the elongated slot 83 in the race 2. This is threaded and is engaged by a threaded portion of one of the ad justingshafts. As is seen in Fig. 2, the adjustii gshaft 9 is mounted in suitable bearings, the central bearing 78 being provided, and this shaft is provided with the right and left handed threads 7 5 79, so that by rotating the. shaft the two guides 14 are. simultaneously ad justed toward or from the center of the machine.

A similaradjusting-shaft 11) operates in the same way upon the lugs 11 at the front ends of the two guides, and, as indicated in Fig. 3,

pivot 55.

' these two adjusting-shafts are operated in unison by being geared to the longitudinal adjusting-shaft 71, mounted in suitable bearings in the frame and provided w th the beveled gears 69 73, which mesh with the beveled gears 68 and 72 on the two transverse adjusting-shafts. The rotation of this 1011- gitudinal shaft by means of the knurled wheel 7 4 simultaneously adjusts the guides, so as to move them toward or from the center of the machine while maintaining their parallel position.

In order to feed the envelops along the runway, feeding tapes 4 may be used, and, as mdicated, these tapes are mounted upon the tape-rolls 5 and 6 at either end of the machine, these rolls being carried by the shafts 7 and 8, which are mounted in suitable bearings. In the operation of the machine each envelop supplied to the front of the machme upon the tapes is rapidly carried forward until its front edge comes into contact with the stop-pins 49, these" pins projecting at that time through slots in the strips 3, as is indicated in Figs. 4 and 5. Each of these stop pins is pivoted to the end of an arm 5t), mounted on the rock-shaft 76. This shaft is oscillated by the rockarm 51, which is connected by the link 53 with the stop-lever 57. This lever, which is loosely mounted on the lever-shaft 30, is normally pulled in one d1- rection by the spring 89, and its lower arm carries the cam-roll 58 which is pressed into engagement with the stop-arm 59,secured to the cam-shaft 48. This cam-shaft, which is rotated by the pulley 82, thus imparts an 1ntermittent vertical movement to the stoppins and brings them. down in front of an envelop at the proper time to secure its alinement.

The arm 52, which is rigidly connected with the rock-shaft 76, is pivoted to the discharge-bar 54, which carries at its lower end the two discharge-rolls 59, mounted upon the These rolls are in such position as to cooperate with the tapes 4, and when they are moved downward by the mechanism described. into the position shown in Figs. 1 and 8 the envelop is pressed downwardupon the tapes, and thus rapidly carried out of the machine, -the stoppins being lifted out of engagement at this time.
